Once you get the linkage gremlins sorted out, you're pretty likely to discover that you've either got one carb too many, or one not enough. The firing order on an inline six makes it perform best with either one, or three carburetors. If you choose the 3-carb route, you'll need carburetors that would work best on a single cylinder engine the displacement of one of the cylinders on the stovebolt six, since only one cylinder at a time is being supplied by each intake port. I'm working on designing a 3-carb setup using Keihin "Constant Vacuum" carbs for an 80 cubic inch Harley Davidson motorcycle.
